kimmygibblershomework:If it were Cortez, it would be Cibola they are referring to, subby, which is in the Hopi/Zuni indian area. Pizarro was the El Dorado goon extraordinaire. Although I have never heard it referred to as Ciudad Blanca or whatever, I guess that is the Honduran legend as it did take many forms. I read a book in middle school that was basically an account of hunting for it (fun read) that told such fanciful stories as 8 sheep fleeces full of gold dust that they were transporting on mule train until ambushed. The buried the bamboo containers with the gold dust are still out there as are the stone ruins of the once gilded city. He had it placed in Brazil, off the Orinoco. Oh well. Good times.

El Dorado was in South America somewhere, commonly believed by Pizarro et al to be in the Colombia/Ecuador region. Sir Walter Raleigh (yes, Roanoke Raleigh, who was in and out of the Tower of London for most of his career) thought it was up the Orinoco River in Guyana, near where Guyana, Venezuela, and Brazil all meet up.

Cibola (or, the Seven Cities of Cibola) were supposedly in the American southwest/northern Mexico somewhere, and are generally believed to be references to pueblo and cave dwellings of that region. Francisco Coronado led the biggest expedition in search of Cibola, going all the way to Kansas before turning back.

La Ciudad Blanca was supposedly the birthplace of Quetzlcoatl, the feathered serpent god. Cortez heard about this city from the Aztecs he conquered, and spent five years or so banging around Honduras looking for the place (and also mixing it up with other Spanish explorers, but that's not relevant).

There was also Ponce de Leon and the Fountain of Youth in Florida, but that's just a stupid story of an idiot getting lost in the everglades.

"We use lidar to pinpoint where human structures are by looking for linear shapes and rectangles," Colorado State University research Stephen Leisz, who uses lidar in Mexico, said in a statement. "Nature doesn't work in straight lines."

Well not always of course, but come on now. Don't make me go on a spiel of naturally occurring straight lines now of all provenances animal, astral, vegetal, and mineral.
